this is easy! I LEARNED IT IN SCIENCE! WERGNER DICOVERED IT. WEGNERS EARLIER THEORY OF CONTINENTAL DRIFT WAS REEXAMMINED AND A NEW THEORY WAS BORN ............................ THE THEORY OF PLATE TECTONICS
One key idea that promoted the theory of plate tectonics was the concept of continental drift, originally proposed by Alfred Wegener in the early 20th century. He suggested that continents were once joined in a single landmass and have since drifted apart. Evidence supporting this theory included the matching geological formations and fossil distributions across continents, as well as the fit of the coastlines. The development of seafloor spreading in the 1960s further solidified the theory by explaining the mechanisms behind plate movement.
Other scientists questioned the theory of plate tectonics initially because there was no known mechanism to explain how continents could move. Additionally, some were skeptical of the idea because it challenged the prevailing belief at the time that the Earth's surface was static and immovable.
Harry Hammond Hess is famous for his contributions to the theory of plate tectonics. He proposed the idea of seafloor spreading, which suggested that new oceanic crust is formed at mid-ocean ridges and then gradually moves away from the ridge. This theory provided key evidence in support of the broader concept of plate tectonics.
One idea used to dispute the theory of plate tectonics is the concept of "geosynclines," which posits that geological features such as mountain ranges and ocean basins are formed by vertical movements of the Earth's crust rather than horizontal movements of tectonic plates. Critics also argue that some geological features can be explained through alternative mechanisms, such as thermal contraction or the Earth's cooling process, rather than plate interactions. Additionally, some geologists suggest that the fossil record and the distribution of certain species do not consistently support the movement of continents as proposed by plate tectonics. However, these alternative theories have largely been overshadowed by the overwhelming evidence supporting plate tectonics.

The idea of seafloor spreading, proposed by Harry Hess in the early 1960s, helped promote the theory of plate tectonics. This idea explained how new oceanic crust is formed at mid-ocean ridges and then spreads out, pushing older crust aside. This process provided a mechanism for how continents move and gave strong evidence for the movement of tectonic plates.

One idea used to promote the theory of plate tectonics was the discovery of matching coastlines and geological features on opposite sides of the Atlantic Ocean, known as "continental drift." This supported the idea that continents were once connected and had drifted apart over time due to the movement of tectonic plates.
The theory of plate tectonics supports the idea of continental drift. It suggests that the Earth's lithosphere is divided into large plates that move over the asthenosphere, which explains the movement of continents over time.
The existance of land bridges between continents
The theory of plate tectonics was developed by a combination of scientists, including Alfred Wegener, who proposed the idea of continental drift, and Harry Hess, who proposed the idea of seafloor spreading. Their work was later expanded upon by researchers like Fred Vine, Drummond Matthews, and J. Tuzo Wilson, leading to the development of the modern theory of plate tectonics.

plate tectonics
The theory of plate tectonics builds on the idea of continental drift by explaining how the Earth's lithosphere is broken into plates that move over the asthenosphere. Plate tectonics also accounts for the movement of not just continents, but also oceanic crust, creating a more comprehensive understanding of Earth's geological processes. Additionally, plate tectonics provides a mechanism for explaining the formation of mountain ranges, earthquakes, and volcanic activity at plate boundaries.
Wegener's idea of continental drift suggested thatcontinents moved, but it did not explain many otherparts of Earth's crust. Today scientists use the theoryof plate tectonics to explain why Earth's features appearas they do.According to the theory of plate tectonics, Earth's lithosphere is broken into about 20 moving plates. The continents and the ocean floor make up the surfaces of these moving plates.
Continental drift is the theory that continents have moved over time, while plate tectonics is the broader theory that explains how the Earth's lithosphere is divided into plates that move and interact with each other. Continental drift was an early idea that eventually led to the development of plate tectonics as a more comprehensive explanation for the movement of Earth's crust.
